摘要:Product and content personalization is now ubiquitous in e-commerce. There are typically not enough available transactional data for this task. As such, companies today seek to use a variety of information on the interactions between a product and a customer to drive personalization decisions. We formalize this problem as one of recovering a large-scale matrix with side information in the form of additional matrices of conforming dimension. Viewing the matrix we seek to recover and the side in...

摘要:Based on a dynamic model of the stochastic repayment behavior exhibited by delinquent credit-card accounts in the form of a self-exciting point process, a bank can control the arrival intensity of repayments using costly account-treatment actions. A semi-analytic solution to the corresponding stochastic optimal control problem is obtained using a recursive approach. For a linear cost of treatment effort, the optimal policy in the two-dimensional (intensity, balance) space is described by the f...

摘要:It is now well understood that social media plays an increasingly important role in consumers' decision making. However, an overload of social media content in product search engines can hinder consumers from efficiently seeking information. We propose a structural econometric model to understand consumers' preferences and costs on search engines to improve user experience under unstructured social media. Our model combines an optimal stopping framework with an individual-level random utility ...

摘要:Many service systems have servers with different capabilities and customers with varying needs. One common way this occurs is when servers are hierarchical in their skills or in the level of service they can provide. Much of the literature studying such systems relies on an understanding of the relative costs and benefits associated with serving different customer types by the different levels of service. In this work, we focus on estimating these costs and benefits in a complex healthcare set...

摘要:The agriculture industry plays a critical role in the U.S. economy, and various industry sectors depend on the output of farms. To protect and raise farmers' income, the U.S. government offers two subsidy programs to farmers: the Price Loss Coverage (PLC) program, which pays farmers a subsidy when the market price falls below a reference price, and the Agriculture Risk Coverage (ARC) program, which is triggered when farmers' revenue is below a threshold. Given the unique features of PLC and AR...

摘要:This paper studies multitier supply chain networks in the presence of disruption risk. Firms decide how much to source from their upstream suppliers so as to maximize their expected profits, and prices of intermediate goods are set so that markets clear. We provide an explicit characterization of (expected) equilibrium profits, which allows us to derive insights into how the network structure-that is, the number of firms in each tier, production costs, and disruption risk-affect firms' profits...

摘要:Empirically, bank equity value is decreasing in the interest rate. Yet (i) many banks do not hedge interest rate risk, and (ii) more than 50% of hedging banks use derivatives to increase exposure. I model a bank's capital structure and show that these facts are consistent with optimal hedging under financial frictions. Novel predictions on the characteristics of banks taking long or short interest rate derivative positions are tested and supported by the data. Therefore, banks' derivatives exp...

摘要:Although many franchisors choose to own some stores and franchise others, attempts to estimate the effect of franchising on store performance are hampered by an important selection issue: The franchisor may choose to assign the least desirable locations to franchisees. I overcome this issue by using a 2007 corporate sale that resulted in all franchisor-owned Applebee's stores in Texas being sold to franchisees as a source of exogenous variation. I first find evidence that both observable and u...

摘要:The patching approach to security in the software industry has been less effective than desired. One critical issue with the status quo is that the endowment of patching rights (the ability for a user to choose whether security updates are applied) lacks the incentive structure to induce better security-related decisions. However, producers can differentiate their products based on the provision of patching rights. By characterizing the price for these rights, the optimal discount provided to ...

摘要:This paper documents new evidence against perfect risk spanning in crude oil futures, and develops an affine futures pricing model that allows for unspanned macroeconomic factors. Compared to previous estimates, the oil spot premium is more volatile and strongly procyclical, which suggests that previous models miss the majority of variation in oil risk premiums. The estimates reveal a dynamic two-way relationship between oil futures and economic activity: productivity shocks are associated wit...
